QNetworkAccessManager incorrectly shuts down localhost connections

steps to reproduce:

1. start localhost http server, streaming data.
2. start client connecting to localhost server, receiving data through QNetworkAccessManager/QNetworkReply
3. change to wifi
4. disconnect from wifi

expected result:
wifi connection or lack thereof does not influence localhost connections
OR
if connection absolutely has to be reset, finish or error signals should be sent from the QNetworkReply so client can reconnect

actual result:

• server receives SIGPIPE (socket closed remotely)
• client receives networksessionstate change signal
• QAbstractSocket is closed by QNetworkAccessManagerPrivate::_q_networkSessionStateChanged(QNetworkSession::State state):
  if (state == QNetworkSession::Disconnected)
  objectCache.clear();
